The Optibelt T5 690 is a timing belt from the Alpha Power series, with a T5 profile, a 690 mm length and a 5 mm pitch. Before you fit a replacement, take a few minutes to inspect the drive and the sheaves.

Check the sheaves for worn grooves, burrs, corrosion or debris that can damage a new belt. Confirm the shafts turn freely, the bearings are sound and the tensioner moves through its full range. Verify that the sheave profile matches the T5 pitch and that the belt runs straight and square in the grooves.

A worn or misaligned drive will shorten the life of any timing belt, including this Optibelt T5 690. Correct any alignment or tensioner issues first, then install the belt and set tension as specified for the drive. Keep the old belt for comparison and note the marking on its back so the replacement matches exactly.
